# `Sidereon.CCSDS.OEM.Covariance`
[🔗](https://github.com/neilberkman/sidereon-ex/blob/main/lib/sidereon/ccsds/oem.ex#L62)

One 6x6 covariance block inside a parsed CCSDS OEM segment.

`matrix` is a row-major list of six six-element rows. `cov_ref_frame` is the
optional `COV_REF_FRAME` override, or `nil` to inherit the segment frame.

# `t`

```elixir
@type t() :: %Sidereon.CCSDS.OEM.Covariance{
  cov_ref_frame: String.t() | nil,
  epoch: String.t(),
  matrix: [[float()]]
}
```
